Ngentsimbi ye-11:30 nge-19 ka-Okthobha ngo-2021, injini yerokhethi eqinileyo ye-monolithic yaseTshayina eyaziphuhlisa ngokwayo ene-thrust enkulu kwihlabathi, umlinganiselo ophezulu we-impulse-to-mass, kunye nokusetyenziswa kobunjineli yavavanywa ngempumelelo eXi'an, nto leyo ebonisa ukuba amandla okuthwala i-solid-carrier yaseTshayina afezekiswe kakhulu. Ukuphuculwa kubaluleke kakhulu ekukhuthazeni uphuhliso lwetekhnoloji yezithuthi ezinkulu nezinzima kwixesha elizayo.
Uphuhliso oluphumelelayo lwee-solid rocket motors alubonisi nje kuphela umsebenzi onzima nobulumko bezazinzulu ezingenakubalwa, kodwa alunakwenzeka ngaphandle kweminikelo yezinto ezininzi zeekhemikhali ezifana neemveliso ze-tungsten kunye ne-molybdenum.
I-solid rocket motor yi-chemical rocket motor esebenzisa i-solid propellant. Iquka ikakhulu igobolondo, ingqolowa, igumbi lokutsha, i-nozzle assembly, kunye nesixhobo sokutsha. Xa i-propellant itshisiwe, igumbi lokutsha kufuneka linyamezele ubushushu obuphezulu obumalunga nama-3200 degrees kunye noxinzelelo oluphezulu olumalunga ne-2×10^7bar. Njengoko yenye yezinto ezikwi-spacecraft, kuyimfuneko ukusebenzisa izinto ze-alloy ezikhaphukhaphu ezinamandla aphezulu ezifana nezenziwe nge-molybdenum-based alloy okanye i-titanium-based alloy.
I-alloy esekelwe kwi-molybdenum yi-alloy engena-ferrous eyenziwe ngokongeza ezinye izinto ezifana ne-titanium, i-zirconium, i-hafnium, i-tungsten kunye ne-rare earths ene-molybdenum njenge-matrix. Inokumelana okuhle kakhulu nobushushu obuphezulu, ukumelana noxinzelelo oluphezulu kunye nokumelana nokugqwala, kwaye kulula ukuyicubungula kune-tungsten. Ubunzima buncinci, ngoko ke ifanelekile ngakumbi ukusetyenziswa kwigumbi lokutsha. Nangona kunjalo, ukumelana nobushushu obuphezulu kunye nezinye iipropati ze-alloy ezisekelwe kwi-molybdenum zihlala zingekho zilungileyo njenge-alloy ezisekelwe kwi-tungsten. Ke ngoko, ezinye iindawo ze-rocket engine, ezinje ngee-throat liners kunye nee-ignition tubes, kusafuneka ziveliswe ngezinto ze-alloy ezisekelwe kwi-tungsten.
I-lining yomphimbo yinto esetyenziswa kwi-lining yomphimbo we-rocket motor nozzle eqinileyo. Ngenxa yemeko yokusebenza enzima, kufuneka ifane nezinto zegumbi lepetroli kunye nezinto zetyhubhu yokutsha. Ngokwesiqhelo yenziwe ngezinto ezidityanisiweyo zobhedu lwe-tungsten. Izinto zobhedu ze-Tungsten zizinto zesinyithi ezipholisa ngomsindo, ezinokuphepha ngempumelelo ukuguquguquka komthamo kunye notshintsho lokusebenza kumaqondo obushushu aphezulu. Umgaqo wokupholisa ubushushu kukuba ubhedu olukwi-alloy luya kunyibilika kwaye luphele kubushushu obuphezulu, oluya kuthi emva koko lufunxe ubushushu obuninzi kwaye lunciphise ubushushu bomphezulu wezinto.
Ityhubhu yokutsha yenye yezona ndawo zibalulekileyo zesixhobo sokutsha injini. Ngokuqhelekileyo ifakwe kwimpumlo yeflamethrower, kodwa kufuneka ingene nzulu kwigumbi lokutsha. Ke ngoko, izinto eziyinxalenye yayo ziyafuneka ukuba zibe nokumelana okuphezulu kobushushu obuphezulu kunye nokumelana nokutsha. Iialloy ezisekelwe kwiTungsten zineempawu ezintle kakhulu ezifana nendawo yokunyibilika ephezulu, amandla aphezulu, ukumelana nempembelelo, kunye ne-coefficient yokwandisa ivolumu ephantsi, nto leyo eyenza ukuba ibe yenye yezona zinto zikhethwayo zokwenza iityhubhu zokutsha.
Kuyabonakala ukuba ishishini le-tungsten kunye ne-molybdenum libe negalelo kwimpumelelo yovavanyo lwenjini yerokhethi eqinileyo! Ngokutsho kweChinatungsten Online, injini yolu vavanyo yenziwe yi-Fourth Research Institute of China Aerospace Science and Technology Corporation. Inobubanzi obuziimitha ezi-3.5 kunye nokutyhala kweetoni ezingama-500. Ngobuninzi betekhnoloji eziphambili ezifana nee-nozzles, ukusebenza ngokubanzi kwenjini kufikelele kwinqanaba eliphambili kwihlabathi.
Kuyafaneleka ukukhankanya ukuba kulo nyaka iTshayina yenze ukuqaliswa kweenqanawa ezimbini eziqhutywa ngabantu. Oko kukuthi, ngentsimbi ye-9:22 ngoJuni 17, 2021, kwaqaliswa irokhethi yokuthwala iLong March 2F ephethe inqwelo-moya eqhutywa ngabantu yeShenzhou 12. UNie Haisheng, uLiu Boming, kunye noLiu Boming baqaliswa ngempumelelo. UTang Hongbo wathumela oosomajukujuku abathathu esibhakabhakeni; ngentsimbi ye-0:23 ngo-Okthobha 16, 2021, irokhethi yokuthwala iLong March 2 F Yao 13 ephethe inqwelo-moya eqhutywa ngabantu yeShenzhou 13 yaqaliswa kwaye yathwala ngempumelelo uZhai Zhigang, uWang Yaping, kunye noYe Guangfu esibhakabhakeni. Yathunyelwa esibhakabhakeni.
